Maintaining the chlorine balance in the pool prevents bacteria from growing in the water. The basic
balance of chlorine to water is a concentration of 3 mg/Liter ( 3PPM).
John has a pool 16 meters long, 5 meters wide and 2.4 meters deep. How much chlorine does John
need to pour into the pool?
Answer:
Step-by-step explanation:
The volume of the pool:
16 * 5 * 2.4 = 192
1 liter = 0.001 cubic meters
There are 192 cubic meters in the pool.
Therefore, John needs to pour 0.192 liters of chlorine into the pool.

C) sum of 9
D) sum of 12
Answer:
7
Step-by-step explanation:
Evaluate and match each expression on the left to its value on the right, when x = 9 and y = 6.
12 - x
x + 3y
4y - 10
1/3xy
Answer:
12 - x= 3
x + 3y = 27
4y + 10 = 34
1/3xy = 18
Step-by-step explanation:
evaluating where x = 9 and y = 6
12 - x
12 - 9 = 3
x + 3y
9 + 3(6) = 9 + 18 = 27
4y + 10
4(6) + 10 = 24 + 10 = 34
1/3xy
1/3(9* 6 ) = 54 / 3 = 18
The values of the expressions are given below:-
12 - x= 3
x + 3y = 27
4y + 10 = 34
1/3xy = 18
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Evaluating where x = 9 and y = 6
1) 12 - x
12 - 9 = 3
2) x + 3y
9 + 3(6) = 9 + 18 = 27
3) 4y + 10
4(6) + 10 = 24 + 10 = 34
4) 1/3xy
1/3(9* 6 ) = 54 / 3 = 18
Therefore, the values of the different expressions are solved above.

-2(x -5) = -16
can someone please answer this asap
Answer:
x = 13
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
[tex](-2)(x) + (-2)(-5)= -16[/tex] [tex]-2x + 10 =-16[/tex]Step 2: Subtract 10 from both sides.
[tex]-2x + 10 - 10 = -16 - 10[/tex] [tex]-2x = -26[/tex]Step 3: Divide both sides by -2.
[tex]\frac{-2x}{-2}=\frac{-26}{-2}[/tex] [tex]x = 13[/tex]Step 4: Check if solution is correct.
[tex]-2(13-5)=-16[/tex] [tex]-26 + 10 = -16[/tex] [tex]-16=-16[/tex]Therefore, x = 13.
Answer:
x=13
Step-by-step explanation:
-2(x -5) = -16
Divide each side by -2
-2(x -5)/-2 = -16/-2
x-5 = 8
Add 5 to each side
x-5+5 = 8+5
x=13

200S+500W≤$100,000 inequality to describe the constraints and (200, 100) is one solution to the inequality.
What is Inequality?A relationship between two expressions or values that are not equal to each other is called 'inequality.
Given,
A farmer is creating a budget for planting soybeans and wheat.
Planting soybeans costs $200 per acre and planting wheat costs $500 per acre.
Let S be the acre of land to plant soyabean and W be the acre of land to plant wheat.
200S+500W≤$100,000
This is the required inequality.
(200,100) is the solution of inequality.
Hence 200S+500W≤$100,000 inequality to describe the constraints and (200, 100) is one solution to the inequality.

Order equivalent equations of 6(h−4) = 3h to solve for h.
Answer:
8
Step-by-step explanation:
6h-24=3h
-24=-3h
divide both sides by negative 3
8 = h
The solution for the given equation is h=8.
What is an equivalent equation?Algebraic equations with equivalent solutions or roots are called equivalent equations. An analogous equation is one that is created by adding or removing the identical quantity or expression from both sides of a given equation. An equation is equivalent if both sides are multiplied or divided by the same non-zero value.
The given equation is 6(h-4)=3h.
The given equation can be solved as follows
6(h-4)=3h
⇒ 6h-24=3h
⇒ 6h-3h=24
⇒ 3h=24
⇒ h=24/3
⇒ h=8
Therefore, the solution for the given equation is h=8.

London is standing in a stadium and has the option of running up a staircase or down a staircase for exercise. The function f(x)=\frac{1}{25}\big(\left|6x\right|+4x\big)f(x)= 25 1 (∣6x∣+4x) will determine how many calories London will burn if she runs up xx steps. Use a negative value for xx if she runs down the stairs. Find and interpret the given function values and determine an appropriate domain for the function.
The domain of a function is the set of input values, the function can take.
The domain of the function is: [tex]\mathbf{(-\infty,\infty)}[/tex]
The function is given as:
[tex]\mathbf{f(x) = \frac{1}{25}\big(\left|6x\right|+4x\big)}[/tex]
The above function represents the number of steps she runs or up down from her current position.
Because she can move in either directions (i.e. up or down), then it means that, the domain of the function is: [tex]\mathbf{(-\infty,\infty)}[/tex]
